Hi

Is there a way of plotting the vertical axis in reverse order. i.e, zero at top of graph and numbers increasing downwards??

thanks

Hi,

say i have an equation that represents the variation of some quanity with height. I naturally want to plot height on the vertical axis and the equation on the horizontal. Is there any way of doing this? E.g, the eqaution below, where z is a vertical coordinate...

> E := proc (z) options operator, arrow; 2000+5*z end proc;

thanks

I am new to this, so should be simple.

i define a function p

> p := proc (x) options operator, arrow; 10*x-20*piecewise(x < 2, 0, 2 <= x, x-2) end proc;
